SPECIFICATION forming part of Letters Patent No. 231,536, dated August24, 1880. Application filed March 3, 1880. (Modei.)

To all whom tt may concern:

Be it known that I, DWIGHT of Derby, in the county of New Haven andState of Connecticut, have invented a new and useful Paper Strip fromwhich to Manufacture Paper Bobbins; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the accompanyingdrawings, in which- Figure 1 is a View, in perspective, of the paperstrip, and Fig. 2 is a view of a bobbin formed from the same.

The invention relates to the manufacture of paper bobbins; and itconsists of a paper strip of novel construction and form, as will behereinafter fully described, and particularly pointed out in the claim.

I produce from paper-pulp a long strip having continuous ribs along itssides. The inner faces of these ribs are beveled, so that when the stripis made up into bobbins the bobbin will have the usual circumferentialflanges at the ends. This strip is preferably wound on a reel convenientfor use in the manufacture of bobbins, and may be fed out and cut off inproper lengths for making the bobbins by any M. CHURCH,

suitable mechanism, and wound or bentaround a spindle until the edges ofthe cut length meet, and then wound with thread to prevent said edgesfrom separating.

Referring by letter to the drawings, A designates the strip made frompaper-pulp, having the continuous ribs to a along its edges madeintegral therewith and beveled on their inner faces, as at B.

[make no claim herein to the process of making the bobbins from thestrip, nor to any mechanism by which the process is applied.

What I do claim as new, and desire to secure by Letters Patent, is-- Asa new article of manufacture, the herein-described paper strip made frompaper-pulp and provided with the continuous ribs a a along its edges,made integral therewith and 45 beveled on their inner faces, as at B,for making paper bobbins, as set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
